实验过程

To a solution of (1-amino-1H-pyrrol-3-yl)phenylmethanone (5.96 g) and N-carbobenzyloxyglycine (6.69 g) in 70 ml of anhydrous DCM and 30 ml of anhydrous dimethylformamide was added DCC (7.22 g). The reaction mixture was stirred at room temperature for 4 hours and filtered. The filter cake was washed with ethyl acetate, and the combined filtrates were evaporated in vacuo. The residual oil was purified by preparative HPLC (silica gel, DCM/ethyl acetate 3:1). Evaporation of the desired fractions afforded a colorless oil, which was crystallized from DCM/ethyl ether yielding the product as colorless crystals (5.96 g), m.p. 144°-145° C.
